Same as Fig. 5, but for the clumps F1 and F2. In the left panel the contours represent integrated intensity map of CH₃CCH 5₂–4₂ line. The velocity range for integration is 75–105 km s^–1, and the contour levels are from 0.45 K km s^–1 (3σ) to 0.8 K km s^–1 (0.9 times peak emission value of F1) with three uniform intervals. Cyan crosses mark the three cores from 3 mm continuum of F1 (as in Fig. 2, right panel).
